LOADING AND DUIVIPING DEVICE.

To all whom it may concern:

Be it known that I, TILDEN J.'BYLER, a citizen of the United States,residing at Blanco, in the county of Blanco and State of Texas, haveinvented a new and useful Loading and Dumping Device; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to the art of excavating and hoisting, and roadgrading mechanism, and 'it more particularly pertains to a new anduseful device for loading gravel and similar materials upon wagons.

The main object of the invention is to utilize the same in connectionwith the ordinary scrapers and teams, that is, the device or loadingapparatus is to be situated at the place where the gravel or similarmaterial is to be obtained, after which the gravel or other material isscraped upon the tray, by the ordinary Scrapers being driven over thetray, thus loading the same. The tray is then hoisted to the desiredheight, and subsequently the wagon, which hauls the gravel to the roadbed or any other location, is driven under the tray, after which thehinged two-part bottom is released, thus allowing'- the gravel or othermaterial to be dumped into the wagon. After the two part bottom of thetray is released the same is again closed and the tray lowered, and theoperations above set forth again repeated.

The device, as herein described and shown in the drawings, may not onlybe used for loading gravel and the like, but may be employed inexcavating, or upon farms, whereby fertilizer and other material may beloaded in wagons. In the drawings, however, there is only disclosed oneparticular form of the invention, but in practical fields this form mayrequire alterations, to which the applicant is entitled, provided thealterations are comprehended by the appended claims.

The invention comprises further features and combinations of partshereinafter set forth, shown in the drawings and claimed.

In the drawin su-Figure 1 is a side elevation of the hoisting andloading apparatus, constructed in compliance with the invention, showingthe hoisting and loading Specification of Letters Patent.

tray in its lowermost position. Fig. 2 is a view similar to Fig. 1,showing the loading tray in its uppermost position, and illustrating awagon in dotted lines beneath the tray, whereby the contents of the traymay be dropped into the wagon. Fig. 3 is a View in end elevation,further disclosing the features of the invention. Fig. 4 is a top planview of the apparatus. Fig. 5 is a View in side elevation of one side ofthe hoisting tray. Fig. 6 is a section view on line 6-6 of Fig. 5.

Referring' to the annexed drawings, 1 designates a rectangular framework, which converges slightly toward the upper portion and is suitablybraced by the transverse and angularly arranged braces 2 and 3. Thebraces are secured firmly in position by means of the various bolts fl.The corner beams of the frame work may be provided at their lower endswith rollers, wheels or the like 5, whereby the frame may be movablefrom place to place. However, only two of the corner beams may beprovided with wheels, while the other two beams may be connected in anysuitable manner to the rear of a wagon, thus making it possible to movethe apparatus from one place to another.

Extending transversely of the upper portion of the frame is a shaft 7upon which drums 8, 9 and 10 are mounted so as to rotate with the shaft,there being two outside drums and one intermediate drum. Connected toand partly wound around the drums 8 and 10 are the cables 11, which passover the pulleys 12, which are secured to the upper transverse braces ofthe frame work. The lower ends of the cables 11 are connected to theside flanges 13 of the tray 14, as illustrated in the drawings.Connected to and considerably wound about the drum 9 is the cable 15, bywhich the shaft at the top of the frame work may be rotated. It will beobserved that the said cables are arranged in such wise, as to permitthe tray 14 to be hoisted, by imparting a pulling action upon the cable15, which will unwind the cable 15 from the drum 9, and in turn willwind the cables 11 upon the drums 8 and 10. The said shaft at one end isprovided with a ratchet wheel 16. Pivoted to sioned pawl 17, which isdesigned to coperate with the ratchet, in order to prevent the cables 11from unwinding from the drums 8 and 10. In other words the pawl preventsretrogression of the said shaft. Connected to one end of the pawl 17 isa pull co-rd 18, which passes over a pulley 19 carried by the frame. Theother end of the cord 18 is connected to a lever 20, which is pivoted atthe base of the frame work. This lever 20 is provided with the usual dog21 to engage the usual form of quadrant 22, whereby the lever 20 may beheld in adjusted positions. The lever 20 is also provided with a handgrip for manipulating the dog 21. JAlso connected to the lever 20 is thepull cord 23, the upper end of which, after having passed over thepulley 2% is connected to a brake lever 25, which is provided with theusual brake shoe 26. When it is desired to allow the tray 14 to lower,the lever 20 is oscillated downwardly, thus releasing the springtensioned pawl from engagement with the said ratchet, which will permitretrograde movement of the said shaft, thus allowing the cables 11 tounwind and the cable 15 to wind. At the same time the shaft is permittedto have a retrograde movement, the brake shoe of the brake lever isapplied against the side of the drum 9, by virtue of the pull cordconnection between the brake lever and the lever 20.

The hoisting tray comprises a rectangular met-al frame having two sideflanges 13, and provided with a two part hinged bottom. To hold the twoparts 27 and 28 of the hinged bottom in closed positions cables 29 areprovided, which at one of their ends are connected to one of the sideflanges 13, while their other ends are wound about and positivelyconnected to a revoluble rod shaft 30, which is mounted in suitablebearings' 31 of the other flange 13 of the tray. Carried by androtatable with the rod shaft 30 at one end thereof' is a beveled gear32, which meshes with a beveled gear 33. The beveled gear 33 is carriedby and rotatable with a vertical shaft 34, which is arranged at rightangles to the shaft 30 and is provided with a crank handle 35. The shaft34 is mounted in bearings 36, as shown in the side elevation of thehoisting tray. A ratchet wheel 37 is mounted upon the shaft 30 so as torotate therewith. Engageable with the ratchet 37 is a spring tensionedpawl 38, and connected to the pawl is a pull cord 39. By imparting apulling action on the pull cord 39 the pawl 38 will be released fromengagement with the ratchet, and by the Virt-ue of the weight of thecontents on the two hinged parts of the tray, the cables 29 will bepermitted to unwind from the shaft 30, thus allowing the hinged parts 27and 28 to open. When the hinged parts open, the contents of the traywill be allowed to dump into the wagon.

After the contents are dumped the v may be again lowered in the mannerhereinbefore stated, for another loading of gravel or other material.

From the foregoing it will be observed that a novel form of apparatusfor hoisting gravel, or other material for loading the same into wagonshas been devised, and one which is found to be practical in every phaseof its operations, and also one which is found to fulfil all therequirements in practical fields.

The invention having been set forth, what is claimed as new and usefulis 1. In combination with a hoisting mechanism, a loading tray includingtwo hinged parts, transverse cables attached to one side of the tray atone of their ends, a rotating member mounted in bearings at the otherside of the tray about which the cables are wound, and means forreleasing the rotating member, a crank shaft arranged at right angles tothe rotating member and including beveled gear connections with themember whereby the same may be rotated for rewinding the cables thereon,thus closing the two hinged parts.

2. In combination with a hoisting mechanism, a loading tray includingtwo hinged parts, transverse cables attached to one side of the tray atone of their ends, for holding the parts in closed positions, a rotatingmember mounted in bearings at the other side of the tray about which thecables are wound, a ratchet movable with the rotating member, a pawl inengagement therewith for preventing rotation of the member, a pull cordfor releasing the pawl from engagement with the ratchet, thus permittingthe two parts to open, a crank shaft arranged at right angles to therotating member and including beveled gear connections with the memberwhereby the same may be rotated for rewinding the cables thereon, thusclosing the two hinged parts.
